BUTTON CLAMP.

Application filed November 12, 1923. Serial No. 674,331.

The present invention relates to new and useful improvements in buttons,and it pertains more particularly to a button for use in connection withbutton-sewing machines.

It is one of the primary objects of the invention to provide a buttonwhich is so constructed that it will be automatically positioned withrespect to a holder of the button-sewing machine.

It is a further object of the invention to construct a button in such amanner that it will be held in such a manner that the needle ot' thebuttonsewing machine will pass through the thread openings in thebutton.

liith the above and other objects in view, reference is had to theaccompanying drawings, in which- Figure 1 is a top plan View of aholding attachment for button-sewing machines, showing a buttonconstructed in accordance with the present invention in place thereon;

Fig. 2 is a sectional view thereof taken on the line 2-2 of Fig. 1;

Fig. 3 is a sectional view thereof taken on the line 8-3 of Fig. 1;

Fig. t is' a sectional view of a modified form of the invention;

Fig. 5 is a sectional view of the modified in Fig. a, and taken at rightan les to such figure;

*ig. 6 is a perspective view of the button.

Referring more particularly to the draw ings, the button holdercomprises a pair of foot members 10, and positioned above said footmembers 10, there is a pair of resilient spring fingers 11. Each ofthese spring fingers 11 has an offset head portion 12, and each of saidoli'set head portions 12 is bent downwardly as at 13, to form aprojecting nose or the like, 16.

The reference numeral 20 designates a button, and such button isprovided with thread openings 21 which pass therethrough as is common inthe art. The body of the button, however, is proiuded with an elongatedrecess or groove 22 which extends prefo5 erably entirely across the faceof the button, the thread openings 21 being spaced with respect to theperipheral edge of the button in the bottom wall of the groove or slot22 formed therein. By this construction, when 60 the button is insertedbeneath the offset portions 12 ot' the spring fingers 11, theprojections 16 will extend into the slotor groove 22, to position abutton relative to the holder and maintain the same in this positionuntil the sewing operation is finished.

In that form of the invention shown in Figs. l and 5 the button isdistinguished from the button shown in the form of the inventionillustrated in Figs. 1 to 3, inclusive, in that the channel or groove 22with which the button is provided is formed on the under face of thebutton, as shown at 25 in Figs. 4- and 5. In this form of the inventionthe toot members 10 are indented as shown at 26, to provide upwardlyextending projections 27 adapted to be received within the channel 25 tomaintain'the position of the button during the sewing operation.

This construction permits of the face 0'1 the button being provided witha suitable design or ornamentation which is not broken or interrupted bythe channel, the latter being formed upon the back of the button ratherthan upon the face as in the first 5 described form of the invention.

From the "foregoing it is apparent that the present invention provides abutton which may be readily inserted and properly positioned withrespect to the button holder 9 of button-sewing machines, and that bythe construction of the button the same is maintained against accidentaldisplacement relative to the holder, thus insuring registration of theneedle openings of the button with the path of travel of the needle.

What is claimed is: 1. In a button-sewing machine, a buttonholdingmeans, said button-holding means comprising a pair of oppositelydisposed 10o resilient fingers and a projection formed on each of saidresilient fingers and adapted to extend into a recess formed in thebutton between the holes of the button and the periphery thereof to holdthe button in position during the sewing operation.

2. In a button-sewing machine, a butt0nholding means comprising a foot,and a plurality of spring fingers adapted to overlie the foot and inspaced relation to each other, said spring fingers having depressedportions forming projections adapted to be received Within a recessformed in the button between the holes of the button and the peripherythereof to prevent movement of the button relative to theb'utton-l'lolding means during the sewing operation.
